Specification of Letters Patent. y

VPatented Aug. 7, 1917.

Application led December 22, 1915. Serial No. 68,112.

To all whom it may concern:

Be it known that I, STANLEY WV. HAYES, a citizen of the United States, residing in Richmond, Wayne county, Indiana, have invented the following described new and useful Improvements in Derails.

The invention relates to derails having a fixed base and a derailing member mounted in the base for transverse up and over movement toward and from the rail, and is concerned more especially with the means for locking the derailing member either open or closed, the object being a simple construction which renders the locking provisions convenient, accessible and the least likely to obstruction by ice or snow.

In the accompanying drawings:

Figure 1 is a side elevation of the derail, with the derailing member in open position upon the rail, shown in transverse section;

Fig. 2 shows the derailing member, in side elevation, and the base in longitudinal section with the exception of its locking portion, which is shown in elevation;

Fig. 3 is a plan view of the open derail; and

Fig. l is a fragmentary cross-section on the line IV-IV of Fig. 1.

The base comprises two lateral plate portions 1 to rest on the tops of adjacent ties, depending flanges 2 which extend downward at the proximate corners of the ties, and upstanding side walls 3 connected at the rear part of the base by an arched roof 5. The said roof is heavily ribbed and thereby braced to the side flanges 1. The body of the derailing member operates within the interior of the base and the derailing block 9 is formed integrally at its forward end. The provisions for guiding the movable member comprise downward projections 13 near its forward end to ride upon curved shelf bearings 6 on the base, lateral projections 17 moving beneath guard ledges 18, and rear side flanges 15 sliding between rounded bearing portions 7 and 8. The portion 12 of the movable member adjacent the derail block is relatively wide and its rear portion 12i1 substantially narrower, the said narrow portion sliding between inward extensions 3a of the side walls of the base. In the top of the forward wide part of the body is a hand-hold 16, enabling the derail to be thrown by hand, while one or more attachment lugs 19 may be provided at the rear end for connection with pipe-line or target-stand.

As to the foregoing features the derail may be and preferably is similar to the construction shown in my prior application filed October 21, 1914, Serial No. 867 ,698, issued as Patent No. 1,185,663, June 6, 1916, to which reference may be had for a more detailed illustration and description.

As in the said application, a padlock hole 20 is formed in the upper portion of one of the upstanding' side walls 3 of the base at the front of the roof 5 and just forward of the front rib thereon, the said hole being adapted to receive the hasp'of an ordinary padlock, represented in dotted lines, and the side wall is recessed around the hole to diminish the length of the latter. n the present instance, however, the base instead of being provided with another padlock hole at the rear, has only the single hole for the padlock, and the said hole is cordinated with two longitudinally spaced abutment faces on the movable member, of which one, marked 21, is for locking the derailing member in its rear or closed position while the other, 3l, is for locking the member in forward or open position, the locking in both cases being effected by the hasp of the padlock inserted in the hole 21 and thereby obstructing movement of which ever abutment portion happens to be against it. As shown in the drawing, the abutment 21 is a generally upward facing surface on the broad portion 12 of the body of the movable member, which, by contacting with said hasp when the derail is closed, prevents the downward projections 13 on the derailing member from riding upward on the ledges 6, with the result that the said member cannot approach the rail, so long as the padlock remains in the hole. The other abutment 31 is provided by the extremity of a rearward proj ection from the wide part of the movable member, this projection being braced by, or comprising, one or more ribs 32 and 33, and having its terminal surface facing genera-lly rearward so as to be set in front of the padlock when the derail is open, as in Fig. 1.

By this construction all the locking is performed in an accessible region well above the ties and adjacent the handhole and in such location locking means are least likely to be affected by freezing rain or snow, and

as there is only one padlocks recess or hole, there is consequently no likelihood that' the padlock may inadvertently be inserted at the wrong place for a particularpositionof the derail block. It will be evident, of course, that the padlock referred to herein is merely representative of any suitable locking member coperatingin a fixed/relation on one member, with the abutmentfaces on the other, as above described, and it will be noted'that it is impossible to insert such member until the derail block is fully seated in one or the other of its two positions, due to the obstruction oifered by the vwall 21a between abutments.

lllhat lis claimed as 4new is the following:

1.In a derail, the combination of a base or standard portion having alocking; hole in its upper and longitudinally intermediate portion, and a derailing member movable in said base and having longitudinally spaced abutmentsA arranged thereon to come into coperative relation to said hole in the open and closed positions of the derailing ,member respectively.

2.111 aderail, a base having upstanding wall/and roof portions and a padlock hole in itsv upper portion in front of the roof and at' one side, in combination with a derailing member movable in the base and provided at one side withlongi-tudinallyspaced abutments respectively placed 4thereon to come into coperative relationto said hole in the open and closed positions-of the derailing member.

3.In a derail, a basey having a padlock hole in its upper and longitudinally intermediate portion, aderailingfmember having npand over movement -in the base toward the rail,saidy member havinga. body which is relatively wide adjacent the derailblock and relatively narrow at the rear,- said 4wider portionaiiordingaan abutment to coperate witha padlock in said hole to prevent movement toward the rail in the closed'condition of the derail, and a rearward projection from said -wider .portion constituting an abutment for similar coperation with a padlock in said hole to prevent movement away from the rail in the open condition.

4. `In a derail, the combination ofa base member and a derailing member mounted therein for transverse up and over movement relatively to the rail, a single locking hole in one of said members and two locking abutment Lfaces on the other member arrangedthereonv to `assume locking relation to. said hole respectively in the closed and open conditions of the derail, and a padlock device in said hole adapted for direct coperation with either of said `faces.

y5. In a derail, a'base and a derailing member lmounted therein for transverse up and overv movement relatively -to the rail, combined with means at the upper and longitudinally intermediate portions of the lbase and derailing-member whereby the latter may be locked in bothv open and closed positions.

6. In a derail, the combination of a base having a locking hole and a derailing member movable in Vsaid base, and having longitudinally spaced abutments arranged thereon to come into ydirect cooperative relation to a padlock. in said hole only in the open and closed positions of said derailing member, and a wall lbetween said abutments adapted to obstruct the passage through said locking hole for all intermediate positions of said derailing member.

In testimony whereof, I have signed this specification in the presence of two witnesses.
